I would go with a phosphate reactor. It allows you to hook it up to a powerhead and hang it on the back of your aquarium and also place other filter media in it such as carbon and phosphate remover.
I wouldn't be too concerned about phosphates though as they are not as important as maintaining a stable and ideal water parameter scenario...Ie. alkalinity, temperature, salinity, pH, ammonia and nitrites. _________ 125gal.w/Mag9.5 return(dual megaflow)>Mag7 pump Aqua Cev180skimmer.Wave2k Hamilton Reefstar(2)250watthqi(mh)pend.a Yellow, Naso Tang Red Lip Blenny Percula Clown Demoiselles Niger Trigger F.
